Two methods DDES, ZDES based on 𝑘 − 𝜔 SST shear stress transport model with compressibility correction are applied in numerical simulation of supersonic base flow, respectively. Third-order MUSCLRoe and fifth-order WENO-Roe spatial scheme are used to investigate the numerical dissipation effects. The calculated results are compared with experimental data. It shows that fifth-order WENO-Roe scheme is more validated than third-order MUSCL-Roe scheme. The comparison of results obtained by DDES and ZDES are also conducted. The results show that ZDES method is better than DDES method in regions near the wall. The complex flow mechanism of supersonic base flow is comprehensively understood, which provides references for the application of RANS/LES hybrid method in the simulation of unsteady supersonic flow.
